Alginic acid fertilizer synergist with ammonia volatilization inhibiting effect and preparation method of alginic acid fertilizer synergist

Abstract

The invention discloses an alginic acid fertilizer synergist with an ammonia volatilization inhibiting effect. The alginic acid fertilizer synergist is characterized by being prepared from the following ingredients in parts by weight: 60-80 parts of seaweed, 2-5 parts of strains, 5-10 parts of carbon sources, 3-5 parts of nitrogen sources, 30-50 parts of water, 1.2-1.5 parts of medium trace elements, 0.4-0.6 parts of soil loosening agent, 2-4 parts of acid soil conditioners and 0.8-1.2 parts of plant growth regulators. The prepared alginic acid fertilizer synergist adopts the pure natural ingredients, so that the alginic acid fertilizer synergist is excellent in environmental protection property, can be degraded completely, and can facilitate a plant to absorb nutrients in soil; an ammonia volatilization inhibiting rate reaches up to 34-45%; the soil loosening agent can loosen the soil; the acid soil conditioner can improve a micro ecological environment of the soil and promote yield increasing of crops; the plant growth regulator accelerates germination and can increase the stress resistance of the crops; and the chelating state medium trace elements can increase the utilization ratio of nutrients and improve the quality of the crops.

Description

technical field [0001] The invention belongs to the technical field of fertilizer synergists, and in particular relates to an alginic acid fertilizer synergist capable of inhibiting ammonia volatilization and a preparation method thereof. Background technique [0002] Traditional chemical fertilizers have single fertilizer efficiency and serious pollution. Long-term application of chemical fertilizers has damaged the farmland ecological environment, soil physical and chemical properties, and soil beneficial bacteria to varying degrees, which has a great impact on the quality of crops. In particular, excessive application of simple chemical fertilizers such as nitrogen fertilizers will intensify soil compaction and reduce soil fertility, making it difficult for the quality and nutrition of crop products to meet people's needs, let alone meet the requirements of green food, and cause serious environmental pollution. [0003] Acidic saline soil can easily lead to soil compactio...

AI Technical Summary

Problems solved by technology

Alginic acid fertilizer has been widely used as an agricultural fertilizer. For example, Patent No. 201110221042.4 The preparation method of micro-ecological alginic acid organic fertilizer synergist. There are also patent documents related to the extraction of alginic acid. The method involves seaweed extraction, but using kelp as raw material, the method of preparing seaweed synergist liquid through solid fermentation method is not yet disclosed, therefore, how to develop a kind of alginic acid fertilizer synergist with ammonia volatilization inhibition and its preparation It is of great practical significance to fully improve and utilize the soil potential to achieve the best effect of increasing crop production and income.
